Question

我有以下json abjects，我喜欢将它们合并到一个对象中，并根据'minute'值缩短子对象。这是可以用JavaScript吗？

[Object, Object, Object]
    0: Object
        Live: "188585"
        Minute: "17"
        Player: "Player A"
        Team: "188564"
        __proto__: Object
    1: Object
        Live: "188585"
        Minute: "26"
        Player: "Player B"
        Team: "188564"
        __proto__: Object
    2: Object
        Live: "188585"
        Minute: "77"
        Player: "Player A"
        Team: "188564"
        __proto__: Object
[Object, Object]
    0: Object
        Live: "188585"
        Minute: "31"
        Player: "Player C"
        Team: "188558"
        __proto__: Object
    1: Object
        Live: "188585"
        Minute: "41"
        Player: "Player D"
        Team: "188558"
        __proto__: Object

我喜欢这样的结果：

[Object, Object, Object, Object, Object]
    0: Object
        Live: "188585"
        Minute: "17"
        Player: "Player A"
        Team: "188564"
        __proto__: Object
    1: Object
        Live: "188585"
        Minute: "26"
        Player: "Player B"
        Team: "188564"
        __proto__: Object
    2: Object
        Live: "188585"
        Minute: "31"
        Player: "Player C"
        Team: "188558"
        __proto__: Object
    3: Object
        Live: "188585"
        Minute: "41"
        Player: "Player D"
        Team: "188558"
        __proto__: Object
    4: Object
        Live: "188585"
        Minute: "77"
        Player: "Player A"
        Team: "188564"
        __proto__: Object

Answer 1

如果您的两个数组已按分钟排序，则可以使用“经典”合并算法。如果没有，您可以使用Array.sort（使用特定的比较函数）连接数组并对结果进行排序。

编辑：这是一个例子：

如果数组未排序：

var result = array1.concat(array2);
result.sort(function(item1, item2) {
    return item1.Minute - item2.Minute;
});

如果数组已排序，则这是一个简单的合并函数：

function merge(array1, array2) {
    var results = [];
    var i = 0, j = 0;
    while (i < array1.length && j < array2.length) {
        if (array1[i].Minute <= array2[j].Minute) {
            results.push(array1[i];
            i++;
        }
        else {
            results.push(array2[j];
            j++;
        }
    }
    while (i < array1.length) {
        results.push(array1[i];
        i++;
    }
    while (j < array2.length) {
        results.push(array2[j];
        j++;
    }
    return results;
}

Answer 2

然后他们看起来像对象的数组。如果是这种情况，您可以使用Array.concat进行连接，并使用Array.sort进行排序。

类似的东西：

// assuming `aba` is the first array, `cd` the second
var result = aba.concat(cd);

result.sort(function(a, b) {
    return a.Minute - b.Minute // implicit conversion in number
});

console.log(result);
